My transcription from Spotify. Most lines are sung in call-and-response fashion, with Nina first singing each line and Frederik repeating it (as I have shown in parentheses) with some overlap. On the lines where no response is shown, they sing together in harmony.

TIME FOR MAN GO HOME Traditional As sung by Nina & Frederik on "Tæt På Vol. 3" (2010)

Time for man go home. (Time for man go home.) Time for man go home. (Time for man go home.)

It's time for man and it's time for beast. (It's time for man and it's time for beast.) Time for man go home. (Time for man go home.)

The bird in the bush he call qua qua qua. (The bird in the bush he call qua qua qua.) Time for man go home. (Time for man go home.)

Time for man go home. Time for man go home.

It's time and it's time for beast. (It's time for man and it's time for beast.) Time for man go home. (Time for man go home.)

Time for man go home. Time for man go home.

Hmm-hmm-hmm. Hmm-hmm-hmm.

[The same recording is also on Nina & Frederik with Louis Armstrong, "Formula for Love" (2013).]

Harry Fox Agency's songfile.com attributes the lyrics to Rufus Callender. The song appears on an album titled West Indian Rhythm-Trinidad Calypsos. No attribution for the melody. Other sources say Rufus Callender (Lord Caresser) made calypso recordings 1937-1949. He was born in Trinidad. Here's his Discography. He recorded "Time for Man Go Home" on Decca 17405 in 1939.
